What the Sun symbolizes
The Sun sits at the center of the natal chart, just as it sits at the center of the solar system. It is the primary light of astrology, and its weight matches that role: the Sun stands for the core of the self, the conscious identity, the will, and the vital force of a person. Where the other planets govern particular functions of the psyche, the Sun is the axis around which everything else turns.
Astronomically the Sun is a star rather than a planet, but the astrological tradition counts it among the planets alongside the Moon - together they are called the luminaries. The Sun shows who a person feels themselves to be at the core, what they are reaching for, and where their individuality comes alive. It is the energy we radiate when we live in agreement with ourselves.
The sign the Sun occupies in the chart is what most people mean by their "zodiac sign." But in the chart the Sun is always completed by a house and by aspects, so the sign alone is never the whole portrait.
The Sun in a person's character
The Sun governs the sense of "I" and the way a person exercises will. A strongly placed Sun gives wholeness, confidence, and an inner center: such a person knows what they want and does not dissolve into other people's expectations. The Sun is tied to dignity, pride, and the wish to be seen and acknowledged.
Through the Sun the creative principle expresses itself - not necessarily art, but in the broad sense the capacity to create and to leave one's mark. The Sun also describes a person's relationship to the father and to authority in general, since the father is traditionally linked to the solar principle.
A strong Sun in the chart
A strong, well-integrated Sun produces a bright and coherent personality. Such a person has a natural charisma, an inner foundation, and a generosity of spirit: they have something to give, and they give it freely. They can lead, inspire, and take responsibility without losing themselves.
A strong Sun is healthy self-worth without strain, the ability to stand at the center without overshadowing others, and loyalty to one's own path. Creative energy and vitality are abundant in such a person.
A weak or challenged Sun
A challenged or weakly expressed Sun often gives a blurred sense of self: it is hard to know what one truly wants, easy to be swayed by others, and tempting to look for support outside oneself. From this come insecurity, a hunger for approval, and a fear of stepping forward.
The other extreme is an inflated ego: vanity, a drive to dominate, a touchy pride. Both point to the same thing - an inner center that has not yet formed. The growth here lies in finding one's footing within and learning to express will without diminishing the people around.
What the Sun rules
The Sun rules the sign Leo and is linked to the 5th house - the field of creativity, love, children, and self-expression. This is fitting: Leo and the 5th house unfold the same theme of radiance, play, and showing one's true self.
Among the planets, the nearest neighbors of the Sun in the sequence of luminaries and planets are the Moon and Mercury. See the full list in the Planets section.
Frequently asked questions about the Sun
What does the Sun mean in a natal chart?
The Sun stands for the core of the self - the conscious identity, willpower, and vitality. It is the center of the chart: the Sun's sign, house, and aspects show who a person feels themselves to be and where their individuality shines.
Is the Sun a planet?
Astronomically, the Sun is a star. In astrology, however, it is counted among the planets and called a luminary (together with the Moon). This does not lessen its weight in the chart: the Sun remains the primary light.
Which sign does the Sun rule?
The Sun rules Leo and is linked to the 5th house. Both the sign and the house carry the themes of self-expression, creativity, and shining as oneself.
What do a strong and a weak Sun mean?
A strong Sun gives a whole, charismatic personality with an inner center of gravity. A weak or challenged Sun shows up as a blurred sense of self, insecurity, and a dependence on outside approval - or, at the other extreme, an inflated ego.
